MCP1501 High-Precision Buffered Voltage Reference Features General Description Maximum Temperature Coefficient: 50 ppm/C The MCP1501 is a buffered voltage reference capable from 40C to +125C of sinking and sourcing 20 mA of current. The voltage reference is a low-drift bandgap-based reference. The Initial Accuracy: 0.1% bandgap uses chopper-based amplifiers, effectively Operating Temperature Range: 40 to +125C reducing the drift to zero. Low Typical Operating Current: 140 A The MCP1501 is available in the following packages: Line Regulation: 50 ppm/V Maximum 6-Lead SOT-23 Load Regulation: 40 ppm/mA Maximum 8-Lead SOIC 8 Voltage Variants Available: 8-Lead 2mmx2mm WDFN - 1.024V - 1.250V Package Types - 1.800V - 2.048V MCP1501 - 2.500V 6-Lead SOT-23 - 3.000V V OUT 1 6 DD - 3.300V - 4.096V GND GND 2 5 Output Noise: 27 VRMS, 10 Hz to 10 kHz 3 GND 4 SHDN (1.024V) Applications MCP1501 Precision Data Acquisition Systems 8-Lead SOIC High-Resolution Data Converters Medical Equipment Applications V DD 1 8 FEEDBACK Industrial Controls GND OUT 2 7 Battery-Powered Devices SHDN 3 6 GND GND 4 5 GND MCP1501 2x2 WDFN* V 1 FEEDBACK 8 DD GND OUT 2 7 EP 9 SHDN 3 GND 6 GND 4 GND 5 *Includes Exposed Thermal Pad (EP).
